Thalictrum lucidum

Creeping buttercup, Ranunculus repens.

Perhaps Lotus corniculatus - Bird's-foot Trefoil

I wasn't implying that you were implying the plant that was growing where it wasn't intended(weed) was useless floral. I also wasnt implying that you were implying that I was implying that you were implying. Capitalist greed has caused the 'useless' attitude towards weeds. The lies and deception of the herbicide companies has permeated our society. They want everyone to feel obligated to kill any plant species that isn't part of their perfectly manicured non native turf grass. Any they will use fear, anger, sadness and shame to do it. We are conditioned to feel ashamed and worried if a broadleaf weed appears Anywhere on our property. They don't have any responsibilty to pay for any of the enviremental damage their products cause. We don't have an old and evolved culture here in the states, and if Americans hear false and misleading information 3 or 4 times they will believe the lies and accept them as truth; rather than go and research the science behind it. Well, that's how it seems anyway. When people believe lies, then they magnify the problem by word of mouth. Parts of Europe are trying to do away with herbicides and pesticides at least. Unfortunately the concept of a lawn was borrowed from Europeans. It's uplifting to see someone thrilled about a weed. The OP might also be limited to growing everything in containers?
